4.2 Most important symptoms/effects, acute and delayed

SYMPTOMS: Symptoms of exposure to this compound include hemolytic Heinz-body anemia, transient reticulocytosis, cyanosis, leukopenia, agranulocytosis, neurotoxicity and pancreatitis. Other symptoms include nausea, vomiting, fever, headache, blood dyscrasias and methemoglobinemia. It can cause liver damage, thrombocytopenia and aplastic anemia. Other symptoms may include arthralgia, bronchospasm, pulmonary eosinophilia, peripheral neuropathy, rashes, hemolysis, gray skin color, tachycardia, epidermal necrolysis, erythroid hypoplasia, hemolysis in people who are deficient in erythrocyte glucose-6-phosphate dehydrogenase, red cell contraction, swing in temperature, rhonchi, pulmonary basal crepitations, increased erythrocyte sedimentation rates, eosinophilia, abnormal lung function, death from severe subacute fibrosing alveolitis, yellow skin and blood serum unrelated to jaundice, burning and itching sensation of the feet and ankles, nocturnal hallucinations, numbness, paresthesia in lower limbs, high stepping gait, incoordination of both lower limbs, impairment of sensation in all modes from the waist down, reversible male sterility, decreased semen quality and adenocarcinomas of the small intestine. This compound also causes necrotic or inflammatory lesions in the liver, heart, kidneys and bone marrow, hematuria, gastrointestinal irritation, maculopapular erythematous skin eruptions, mental and visual disturbances, sensitivity reactions, urticaria, pain on urination, oliguria or anuria with azotemia, purpura, conjunctival injection, bullous lesions of the skin, petechiae, jaundice, increased erythema or injury from sunlight and irreversible neuromuscular and central nervous system changes. Other symptoms are hypersensitivity reactions involving the lungs. Exposure may cause Stevens-Johnson syndrome, Lyell`s syndrome, salicylism, pulmonary reaction with associated pulmonary infiltration, reversible oligospermia, macrocytosis, erythroid and megakaryocytic aplasia, megaloblastic anemia, bloody diarrhea, hepatotoxicity, tracheolaryngitis, dyspnea, folic acid reduction, lupus erythematosus, Raynaud`s syndrome, scaling skin eruption, lymphadenopathy, orange-yellow urine and neutropenia. Ataxia may also occur. ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes of nitrogen oxides and sulfur oxides.

4.3 Indication of immediate medical attention and special treatment needed, if necessary

... Alkalinize urine. If kidney function is normal, force fluids. If anuria is present, restrict fluids and salt, treat appropriately. Catheterization of the ureters may be indicated for complete renal blockage by crystals. The low molecular weight of sulfasalazine and its metabolites may facilitate their removal by dialysis. For agranulocytosis , discontinue the drug immediately, hospitalize the patient and institute appropriate therapy. For hypersensitivity reactions, discontinue treatment immediately. Such reactions may be controlled with antihistamines and, if necessary, systemic corticosteroids.

Eye/face protection

Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Skin protection

Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

• Toxicity to daphnia and other aquatic invertebrates: no data available
• Toxicity to algae: no data available
• Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Sulfasalazine is reported to be non-biodegradable during sewage treatment(1-3); however, data supporting this conclusion have not been found. Sufasalazine undergoes azo reduction by microflora in human intestine to form sulphapyridine 5-aminosalicylate(1,4).

12.3 Bioaccumulative potential

An estimated BCF of 3.2 was calculated for sulfasalazine(SRC), using an estimated log Kow of 3.8(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of sulfasalazine can be estimated to be 1800(SRC). According to a classification scheme(2), this estimated Koc value suggests that sulfasalazine is expected to have low mobility in soil. However, estimated pKa values of 6.5 (sulfonamide nitrogen) and 2.3 (carboxylic acid)(SRC), calculated using a method based on linear free energy relationships and perturbed molecular orbital theory(3), indicate that this compound will exist primarily as an anion in the environment, and anions generally have higher mobility in soils than their neutral counterparts(4).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
